To all whom it may concern:

Be it known that I, RAYMOND C. PARENT, a. citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Soldering-Irons, of

i which the following is a full, clear, concise,

and exact description, reference being had to the accompanying drawings-forming a part of this specification.

My invention is an improvement in soldering-irons of that particular type in which the head or soldering-point is heated by means of a burner forming part of the implement and supplied with liquid fuel from a reservoir in the handle, commonly known as self-heating soldering irons.

The principal object of my present invention is to provide an implement of this general character which is simple and compact in construction,easily and conveniently operated, and in use will efiect the heating of the head or iron uniformly at any temperature desired so as to greatly facilitate the operation of soldering all kinds of work for which the ordinary soldering-iron is adapted.

A further object of my invention is to provide a self-heating soldering-iron in which provision is made for supplying liquid fuel from the handle to the burner irrespective of the osition in which the implement is held, whereby fuel will be fed to the burner to maintain the head or iron properly heated when the implement is turned upside down for overhead work,

Another object of my invention-is to so construct the soldering implement that when the soldering-head or iron is removed a very handy and effective blow-torch is furnished which may be used for accomplishing any kind of work required of a device of such nature.

Other object's and advantages of my invention will hereinafter appear, and what I particularly claim'as my invention and desire to protect by Letters Patent is more specifically set forth in the appended claims.

In the accom anying drawings, form ng apart hereof: igure' 1 is a side elevation of a self-heating soldering-iron constructed in accordance with my invention. Fig. 2 is a. longitudinal sectional view through the Same. Figs. 3 and 4 are detail views of disks located in the reservoir-handle to confine packings therein. Fig. -5 is .a detail side elevation of the combined vaporizer and burnertube. Fig. 6 is a plan view of the same,'and Fig. 7 is a transverse sectional view through the vaporizer. 1 Like numerals of reference indicate like parts in all the figures ofthe drawings.

Referring to the drawings, 8 designates the-handle of the implement which is made hollow andof' a size to hold .an ample-supply of the liquid fuel, as'gasolene, employed ror heating the head or point of the soldering-iron and as the liquid fuel is-"fed'unde'r pressure to the burner said handle is provided at 'its' upper end with an fair-pump 9,

ofany' conventional type of construction operated in the usual'manner by a plungerrod 10 havinga gripping knob 11. For convenience'in attaching. the air-pump to the handle it is 'carriedby a screw-cap 12 which closes :the outer end of said handle, these parts'being removable for the purpose of filling the. reservoir. The cap may be, and preferably is, provided with a wrench receivlngportion 12 and interposedlbetween the cap and reservoir handleis' a leather washer 13, to provide a tight joint.

The reservoir handle is enlarged at its lower portion, as shown,'to-provide a larger fuel capacity below the gripping portion and to receive certain means, hereinafter described, for accomplishing the feed of liquid fuel or gasoleneto the: burner when the implement 'istu'rned upside down. The bottomof the reservoir handle is in the form of a thick cup-shaped disk I4, with an annular recess at its upper outer edge to, receive the lower end of the cylindrical body portion of said handle, and a deeper-annular recess at its lower edge to receive the upper end'fiof a yoke 15, which carries the burner and soldering-head of the implement. The disk or bottom is welded in the cylindrical portion ofthe' handle and the yoke is detachably connected thereto by means of screws which are threaded into said disk, permitting the yoke to be removed from the handle so that the burner and other parts secured therein may be withdrawn through the upper end for examination and repair.

Within the yokje 'near the upper end thereof is located a conventional form of burner accessible through opposite openings in the yoke, andv throu h these openings the required'supply 0 air passes to the burnertube.-26 to mix with the gasolene discharged from the burner. The perforated burnertubeor mixing-chamber 26 is located within the yoke a short distance below the burner, and in the present instance is combined with an, auxiliary reservoir 23 from which it dependsgsaid auxiliary reservoir being in the form of a hollow ring through the center of which the gasolene and air pass to the burner-tube or mixing chamber.

The gasolene or other liquid fuel is conducted to the auxiliary reservoir by a pipe 24 extending from-the lower part of the reser'voir'handle, and is fed from said auxiliary reservoir to the burner by means of a short pipe 25. By this arrangement a supply of gasolene for the burner is maintained in the auxiliary reservoir and heated by the combustion in the burner-tube so that it will quickly vaporize when discharged from the burner.

Belowthe auxiliary reservoir or vaporizer and surrounding the perforated burner-tube the yoke is. provided with elongated air openings 27 extending to the ring 28 which forms the end of the yoke and end of the blow-torch'when the implement is used as such, andinto this ring the reduced end of the soldering-head onpoint 29 fits. The soldering-head is chambered, as shown, to receive the'flame from the burner and is detachably connected by a screw 30 thereon fitting into a bayonet-slot 31 in the aforesaid ring, so that soldering-heads of different sizes may be used in connection with the implement and readily applied, as well as permitting the implement to be used as a blow-torch when the soldering-head is re moved, as will be understood.

The ring 28 of the yoke and the body of the soldering-head are provided with suitably disposed air-inlet holes, and the soldering-head is also provided near its point with outlet holes leading from the inner end of the chamber, the latter terminating to leave a suiiicient body of metal to retain heat and produce an effective soldering-point.

In order to insure asupply of gasolene to the burner when the implement is turned point upward for overhead work in use as a soldering iron, or general use as a blowtorch, a packing of preferably raw cotton is placed in the lower end of the reservoirhandle and the supply pipe 24: fromwaporizer extended into it. This packing, 32, is held in place by a perforated disk 33 secured in the hollow handle, and in addition to the aforesaid packing I employ a second packing 35 on which is placed a preferably leather disk 34 through which the gasolene permeates to thoroughly saturate the packings, whereby said packings retain a supply of the fuel that is gradually fed to the burner when the implement is held upside down and the gasolene in thehandle flows away from the leather disk; in other wordsthe gasolene will permeate the leather disk when the point of the implement is turned upward. I have found by actual tests that when the handle is provided with the pack ing and leather disk the burner device will maintain an effective flame with the implement turned upside down for quite a'long while, although the body of gasolene in the handle is then away from the leather disk and compressed air in between. To protect the inner end of the supply pipe 24, where it terminates in the packing 32, it is provided with a perforated cap 36. When the iron is held upside down, or in an inverted position, the mainsupply of gasolene will obviously fall away from the packing and disks and the compressed air within the reservoir will assume an uppermost position. The P30]?- ing and disks 32, 33,- 34 and 35 form a barrier, when the iron is held in such inverted position, between the air and the bulb end 36 of the feed pipe 24 so as to prevent air from enterin said feed pipe and consequently interrupting the flow of fuel'to the burner.

In such inverted position of the ironalso which assists in squeezing out or feeding the fuel trapped or held in the packing 32 into the bulb head 36.

The operation of the implement will be readily understood by those skilled in this art, for after the burner is started by heat ing the vaporizer in any suitable manner, as by an open flame from burning gasolene, usual in devices of this character, the soldering-head will be kept heated by the flame from the burner and the degree of heat may be regulated by mani ulating the valve in the manner hereinbe ore described. After proper adjustment of the valve, the solderhead will be kept at a uniform degree of heat so that the operator may use the implement continuously, and by the particular constructionof the feeding device for the gasolene said implement may be held in any gosition for soldering work of all kinds.

y simply removing the soldering-head the implement is ready for useas blow-torch, and in this instance'thc flame is discharged from the end'of the yoke.

Instead of detarhably connecting the soldering-head-to theyoke'by means of screws and bayonet-slots, as herein shown and described, I may employ any other well known form of connection; audit will be apparent, also, that other details in the general construction ofthe implement may be changed or modified within the scope-of my claims.
